What is the pressure at 45000 feet?
Example ? Air pressure at Elevation 10000 m
Altitude Above Sea Level Absolute Barometer feet metre inches Hg 35000 10668 7.04 40000 12192 5.52 45000 13716 4.28
How do you find pressure from altitude?
To calculate pressure altitude without the use of an altimeter, subject approximately 1 inch of mercury for every 1,000-foot increase in altitude from sea level. For example, if the current local altimeter setting at a 4,000-foot elevation is 30.42, the pressure altitude would be 3,500 feet: 30.42 ? 29.92 = 0.50 in.
What will be the atmospheric pressure at an altitude of 5000m?
Relationship Between Altitude and Pressure
Altitude above Sea Level Absolute Atmospheric Pressure 5000 0.95 84.3 6000 1.14 81.2 7000 1.33 78.2 8000 1.52 75.3
How much does air pressure change with altitude?
Since more than half of the atmosphere?s molecules are located below an altitude of 5.5 km, atmospheric pressure decreases roughly 50% (to around 500 mb) within the lowest 5.5 km. Above 5.5 km, the pressure continues to decrease but at an increasingly slower rate.

How do you find density with pressure and height?
P=h?g P = h ? g , where P is the pressure, h is the height of the liquid, ? is the density of the liquid, and g is the acceleration due to gravity.
What is the temperature at 15000 feet?
U.S. Standard Atmosphere Air Properties ? Imperial (BG) Units
Geo-potential Altitude above Sea Level ? h ? (ft) Temperature ? t ? (oF) Dynamic Viscosity ? ? ? (10-7 lb s/ft2) (10-7 slug /(ft s)) 15000 5.55 3.430 20000 -12.26 3.324 25000 -30.05 3.217 30000 -47.83 3.107
How do you calculate air pressure?
Atmospheric pressure is the pressure caused by the mass of our gaseous atmosphere. It can be measured using mercury in the equation atmospheric pressure = density of mercury x acceleration due to gravity x height of column of mercury.
What happens to pressure as altitude increases?
As altitude rises, air pressure drops. In other words, if the indicated altitude is high, the air pressure is low. As altitude increases, the amount of gas molecules in the air decreases?the air becomes less dense than air nearer to sea level.
What is the air pressure at 10000 m?
Example ? Air pressure at Elevation 10000 m. The air pressure at altitude 10000 m can be calculated as. p = 101325 (1 ? 2.25577 10 -5 (10000 m)) 5.25588. = 26436 Pa. = 26.4 kPa. vacuum.
What is the air pressure at sea level?
Using ISA standards, the defaults for pressure and temperature at sea level are 101,325 Pa and 288 K. Altitude above Sea Level. Absolute Atmospheric Pressure.
What is the saturation of air at 10, 000 feet?
At 10,000 feet above sea level, the normal saturation for a human breathing regular air is 87 percent. Go to 18,000 feet without supplemental oxygen and the saturation drops to 80 percent (thanks to the partial pressure of oxygen being just 21 percent of the atmospheric pressure at any altitude).
How to calculate air pressure at an altitude?
The altitude at a given air pressure can be calculated using Equation 1 for an altitude up to 11 km (36,090 feet). This equation can be arranged to also calculate the air pressure at a given altitude as shown in Equation 2.

How do I move an iPhoto library to a folder?
So, you must be in the Events view in iPhoto and select the event you want to export. Then choose File / Export to folder, choose ?JPEG? in ?File type? (or ?kind?) (if you have created image metadata see my next note) and then click ?Export? and then choose your destination folder which is FROM-IPHOTO .
How do I move iPhoto library to external hard drive?
Open iTunes and connect your iPod touch to your computer. Click on the iPod Touch along the top pane in iTunes and then click on the ?Photo? tab. Choose ?Sync photos from? and select ?iPhoto.? iTunes and iPhoto communicate and all of your iPhoto library, as stored on your external hard drive, is listed in iTunes.
What is the difference between iPhoto library and Photos library on Mac?
That said, the difference is simple: iPhoto makes changes only to the iPhoto Library. Photos makes changes only to the Photos Library. At some point in the future (or now?) you might decide that you no longer use iPhoto, and then you can delete that Library.
How do I export my photo library?
